REEDING-MACHINE.

Specication of Letters Patent.

Patented Dec. 29, 1908.

Application filed October 10, 1907. Serial No. 396,765.

To all 'whom it may concern: t

Be it known that we, OTTO SCHULER and RUDOLPH GLAsER, both citizens ofthe United States, and residents of Patersomin the county of Passaic andState of New Jersey, have invented a new and Improved kReeding-Machine,of which the following is a full, clear, and exact description.

rlhis invention relates to reeding machines, and is particularly usefulin warping or harnessing looms for-weaving textile fabrics.

An object of the invention is to provide a simple and efficient reedingmachinev Aby means of which the warp threads used in textile looms canbe easily and expeditiously inserted in the slits of reeds use d inconnection with these looms.

A further object of the invention is to provide a device of the classdescribed which is automatic in its operation, which can be easilycontrolled by the weaver or operator of the loom, and by means of whichwarp threads can be rapidly inserted in the successive slits of thereed'. t

A still further object of the invention is to provide a reeding machinewhich automatically separates the wires orvdentsof a loom reed, insertsa thread knife between the separated wires or dents, maintains the knifein this position until the operator attaches a warp thread to the same,whereupon the knife with the thread'v is drawn through the reed and thenremoves the thread from the knife and inserts the latter through thenext successive slit of the reed.

The invention` consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims. Y

Reference is to be had to the accompanying drawings forming apart ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in whichl Figurey 1 is a planview of our reeding machine; Fig. 2 is a side elevation of the device,showing certain of the parts in di'ere'nt positions in dotted outlines;Fig. 3 is a similar view showing certain of the arts in differentpositions; Fig. 4 is a side e evation of a detail of the controllingmechanism; Fig. 5 is a plan view of the part of the mechanism forseparating the wires or dents of the reed, and showing a number of thewires or dents in cross-section; Fig. 6 is a side elevation of the wireor dent separating member and Fig.

7 is a side elevation of a part of the machine and shows an electricmotor for driving the same.

Before proceeding to a more detailed explanation of our invention, itshould be under'stood that reeding and harnessing in textile weaving aresubsidiary processes in placing the warp in proper position on the loom;these processes consist in putting each warp thread through its properslit in the reed rzlind he method of reeding commonly in use at thepresent time consists in manually drawing the warp threads through theslits of the The latter is manipulated by an assistant operator orweaver who inserts the knife by hand between the successive adjacentairs of reed wires or dents and holds the knife in position until theweaver places awarp thread in a recess of the same, whereupon theassistant draws the knife through the reed and thus properly positionsthe thread. The assistant then ,frees the Vknife from the thread andinserts the instrument in the next slit. This operation is a tedious andexpensive one, and it is one of the principal objects of `our inventionto provide a labor-saving device that performs the operationautomatically. Our machine includes a thread knife which isautomatically inserted successively in the slits of the reed, and isheld in position there until the weaver has placed his thread in therecess or notch of the knife and has set the actuating mechanism inoperation by manipulating the knife in a certain manner, the knifecontrolling the actuating mechanism for this purpose. The machine thenwithdraws the knife through'the reed and a suitable member frees it fromthe thread. The knife is then advanced toward the reed and passesthrough the next successive slit of the latter, whereupon the operationsare repeated. Thewires or dents of the reed are successively separatedby a suitable device coacting with the knife and the threadremovingmember. We prefer to employ an electric motor as the actuating means forour machine, as Vwill appear more clearly hereinafter.

Referring more particularly to the drawings, 1 represents a suitablebase or support yupon which the machine is mounted. Near the forwardedge, the base 1 at the opposite sides has bearings 2 in which is revoluy arranged a transverse shaft 3 having an eccentric or cam section 4.The shaft 2 has a handle 5 by means of which it can be manuallyoperated. Brackets 6 are provided at the opposite sides of the base andcarry a rigid transverse shaft 7 upon which is slidably mounted a reedcarriage 8 by means of a suitable opening in the body of the same. Thereed carriage extends over the cam section 4 of the shaft 3 and has anupwardly disposed part 9 constituting one of the jaws of a reed holder;the other jaw 10 of the holder is adjustably mounted upon the carriageby means of a thumb-screw 11. The reed 12,

'which can be of any preferred or common form and preferably comprises aframe 13 and Wires or dents 14, is mounted upon the carriage 8 by meansof the holder jaws and the thumb-screw. A helical spring 15 is arrangedupon the shaft 7 between the carriage 8 and one of the brackets 9 andtends to slide the carriage longitudinally of the shaft 7.

At the side of the shaft 7 remote from the reed, the base 1 has twoalined pivot brackets 16 and 17 which carry swinging links 18 and 19respectively, pivoted upon the brackets by means of pins 2O or in anyother suitable manner. The links 18 and 19 at the upper ends have anelongated bar 21a which is pivotally secured to the links by means ofpins or rivets 22 and which carries, by means of screws and s acingcollars 21", a thread knife 21. The ink 19 has a slot 23 at its upperend, through which the pin 22 passes and which permits a limitedmovement of the connecting bar and the knife longitudinally of the link.The knife 21 has a stud 24 to which is secured a helical spring 25, theopposite end of the latter is secured to a stud 24 of the link 19, andthe spring thus serves to hold the knife at the lowest limit of itsmovement longitudinally with respect to the link 19. At the forward endthe knife has an inclined recess or notch 25, adapted to receive a warpthread 26, and serving to hold the thread while it is being drawntirough the reed. rlhe notch 25 is at the upper edge of the knife. Nearthe opposite end, though at the under edge, the knife has a notch 27,for a purpose which will appear hereinafter. Preferably upright frames28 secured together by cross bolts 29, are mounted upon the base 1 andhave revolubly arranged therebetween a shaft 30 carrying a rigid drivingpulley 31 and a pinion 32 5 the latter is in mesh with a gear-wheel 33mounted upon an adjacent shaft 34. The latter extends beyond the frames28 and at the extremity has a rigid crank disk 35. A connecting rod 36is pivn otally mounted upon the crank disk and the link 19 and servesoperatively to oin these parts. Thus, as the shaft 34 is driven from theshaft 30 the knife is reciprocated by means of the links, the connectingrod and the crank disk. The driving pulley 31 is connected by means of abelt 37 with a prime mover which consists of an electric motor A havinga pulley A in the form. of the device illustrated in the accompanyingdrawings, and as shown most el arly in F ig. 7. A further shaft 38 isrevolubly earried by the iframe 28 and extends laterally therebeyond,having at the end a rigid bevel gear 39. rl`he shaft 38 has a gear wheel4t) in mesh with the gear wheel 33, from. which it is driven. A standard41 is carried by the base 1 and is provided at its upper end with abearing 42 in which is arranged a revoluble shaft 43. The latter hasrigid collars 44 at each side of the bearing and is held revolubly inposition thereby. At one end, the shaft 43 has a bevel gear 45 in meshwith the similar gear 39. Near the shaft 3, the base 1 has an upright 46which provided with a laterally extended cross-member 47 rigidly, thoughremovably, mounted thereupon. T he cross-member has its ends laterallydisposed and formed into bearings in which is revolubly carried aspindle 48, provided with a bevel-gear 49 in mesh with a bevel-gear 50mounted at the end of the. shaft 43. The latter extends through asuitable opening in a support 51, carried by the cross-member 47. At oneend, the. spindle projects beyond the extremity of the. cross-member andhas a head 52 which serves to limit its movement. At the other end,which is similarly extended beyond the cross-member, the spindle carriesa rigid disk 53 which constitutes the reed wire or dentseparatingmember. The disk 53 is split near the rim and has the edges 54 of thesplit overlapping. Thus, the periphery or edge of the disk is spirallydisposed, and when. the disk is revolved the spiral edge has a screwlikeaction which successively separates the dents of the reed. The disk, in`operation, has its edge inserted between two of the reed dents, and asit revolves one of the dents passes into the spiral slit, and thus theedge or the disk passes from one side oi' the dent to the other;consequently, successively engaging the slits between the adjacent dentsof the reed.

A journal frame 55 is carried by the base 1 adjacent to the knife, andtherein is pivotally mounted a shaft 56 at one end of which is abevel-gear 57 in operative engagement with a similar gear 58 rigidlycarried by the shaft 34. The shaft 56 has an extension 59, the end ofwhich is laterally disposed to form an arm 60. The arin 60 when theshaft 56 is driven :from the shaft 3 has a rotary movement and sweepsaround the forward end of the knife to free the saine out difficulty.The arrangement of 'the' weaver places the warp vthread in Aposition fparts is such that the arm swings around the point of the knife as thelatter nears the end of its backward movement, and when the knife istraveling forward or through the reed in either direction the arm 60 ismoving incperatively with respect to the knife.

bell crank lever 61 is pivoted by means of abracket 62 upon the base 1.The upwardly extending arm 63 of thelever constitutes a stop and isarranged to be engaged by.

the notch 27 of the knife. The other arm 64 of the lever carries acontact 65 which is suit-V ably insulated from the lever by means ofblocks 66 of hard rubber or the like. The contact 65 serves to effect anelectrical connection between terminals 67 provided with binding posts68 bymeans of whichthe terminals can be included in the circuit of thedriving motor. It will be understood that when the contact 65 connectsVthe terminals, current can flow yin the circuit to drive the motor;whereas, when the `contact is raised the circuit isbroken and the motoris inoperative. A lever 69 is pivotedupon a support 70 carried by thebase 1 and has at'one end an idler pulley 71 and at the opposite end aweight 72. The latterV has a slot 72EL through which extends the end 7 3of the bell crank lever arm 64. 4The end 75 of the arm 63 ofthe bellcrank lever is twisted laterally in order to present a suitableengagingsurface for th shoulder of the knife notch 27. A stop 61 L serves tolimit the upward movement of the bell crank lever.

The operation of.our invention is as follows: When the contact 65effects electrical connection between the terminals 67, the motor isactuated anddrives the pulley 31 by means of the belt 37. When thecontact is in an operative position the bell crank lever arm 64 islowered, consequently the weight 72 is also lowered and the lever 69 isso positioned that the idler'pulley 7,1 presses upward against the lowerrun of the belt 37 and tightens the same so that the motor can drive thepulley 31. As the pulley revolves it actuates the shaft 34 through theconnecting gears and this drives the knife forward through the reed. Asthe knife advances it engages the arm 63 of the bell crank lever andpulls the same forward, thereby raising the arm 64 and breaking thecircuit. rl`he motor is thus stopped and atthe same time the idlerpulley is disposed so that the belt is permitted to loosen and isrendered inoperative with respect to the pulley 31. This feature is ofimportance as the motor may continue to rotate for a short time owing toits acquired momentum and 4thus the stopping of the device would not beinstantaneous; however, when the belt is loosened in this way the movingparts stop at once. The knife, which has been projecting through thereed remains in this position until thel circuit.

the weight 7 2 swings the bell crank lever into position with thecontact closing the motor At the same time, the belt 37 is tightened andtherefore, as soon as the motor begins to operate, the belt drives thereeding machine. The movement of the knife is then continued and itwithdraws from the reed, carrying through the same the thread 26.Meanwhile, the arm 60 has been swinging toward the knife and as thelatter withdraws from the reed the arm passes around the point of theknife and removes the thread. At the same time the separating member hasinserted its edge between the succeeding pair of reed dents and as theknife again approaches the reed it is inserted in this succeeding slit.1t will be understood that the knife and the separating member arenecessarily arranged in the same plane. When the knife is againprojected through the reed `the bell crank lever has been operated andthe motion ofthe machine ceases.- The same operations are then repeateduntil a sufficient number of warp threads has been inserted in the reed.

The reed carriage 8 can be raised or lowered to permit the engagement ordisengagement of the reed and the separating member by means of therevoluble shaft 3. As the latter is swung in one direction the camsection raises the carriage and brings the reed into engagement with theseparating member. W hen this movement of the shaft is reversed the reedis withdrawn from the separating member. It will be understood that thespring 15 serves to advance the carriage as the successive reed slitsare spread by the separating member.
